Oral warty dyskeratoma of the retromolar trigone: An unusual presentation of a rare lesion

SCC: squamous cell carcinoma WD: warty dyskeratoma INTRODUCTION Warty dyskeratoma (WD), also known as isolated Darier disease or focal acantholytic dyskeratosis, is a rare mucocutaneous lesion. It usually presents as a solitary, asymptomatic umbilicated papule, most often in the head and neck region of middleto older-age adults. A slight male predilection has been observed. When it occurs in the oral cavity, WD is most commonly seen on the hard palate and alveolar ridge. Fewer than 50 cases of oral warty dyskeratoma are reported. Here we present a case of WD occurring on the left retromolar trigone in a 78-yearold man.
